1. Mac App Bounces But Doesn't Start Youtube

So my IMac running 10.6.3 has developed a bit of a problem. When a launch certain apps, the icon just bounces and the app never launches. I end up having to force quite and restart to get the app to work. Other apps freeze up (sarfari and chrome) and I have force quit and restart. then there is VLC which launches plays media then freezes. All of these are solved by restarts. Seems if i let the machine fall asleep, then all these bugs resurface. My first solution was to create a new user and delete the old one as my 'backup' username seemed to work fine. this did indeed solve many of my problems but now different apps have developed bugs. Should I just reinstall the OS?

1. Press the power button on your Mac. Every Mac has a power button, usually marked with a power symbol . Then check for signs of power such as these:
   • Sounds, such as from a fan, hard disk, or other startup sound
   • Lights, such as from a backlit keyboard, Caps Lock key, or sleep indicator light
2. If your Mac has no signs of power, start by making sure that it's receiving power:
   • Make sure that your power cable is undamaged and securely plugged into your Mac and a working electrical outlet. If you're not sure about the outlet, test it with a lamp or other device.
   • If you're using a Mac notebook, make sure that it's using the correct power cable and adapter, and that it has been plugged in for about 5 minutes, which is long enough to provide a usable battery charge. Learn how to troubleshoot USB-C power adapters or MagSafe power adapters.
   • If you're using an external display, make sure that it's turned on, securely connected to your Mac, and isn't experiencing any video or display issues.
3. Then try these solutions, whether or not your Mac has signs of power:
   • Press and hold the power button on your Mac for 10 seconds, then press it again.
   • Reset the System Management Controller (SMC).
   • Make sure that your display's brightness is turned up. Mac notebook computers have a Brightness Up key on the built-in keyboard.
   • Unplug all accessories from your Mac, including printers, drives, USB hubs, and mobile devices. (You could have an issue with one or more of those devices or their cables.) Once more, press and hold the power button for 10 seconds, then press it again.
4. If your Mac has signs of power but the screen remains blank, try the steps for when your Mac starts up to a blank screen.
